“What was your reaction when you saw the blood? This simple question can stimulate the witness to describe the scene to us, adding new elements. In a general way, during all the interviews, it is a question of keeping the focus on what the person saw or heard. To that end, an inalterable rule: to remain fixed on the objects of everyday life, all the while respecting the viewpoint of the witness in such a way that does not bias the witness’s account. That, incidentally, is the irreplaceable contribution of oral history, which offers precisely the possibility of “looking” through previously unseen points of view.” – Father Patrick Desbois, “The Witnesses of Ukraine or Evidence from the Ground: The Research of Yahad-In Unum” (collected in The Holocaust in Ukraine: New Sources and Perspectives, 2013) (emphasis in original)
